Chemical Structure

Clotrimazole EP Impurity F CAS 15469-97-3 chemical structure

Description

Structurally, Clotrimazole EP Impurity F (C22H18N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 310.39 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Clotrimazole EP Impurity F (CAS 15469-97-3) is a certified pharmaceutical impurity reference standard with the molecular formula C22H18N2 and a molecular weight of 310.39 g/mol.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Clotrimazole EP Impurity F meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
